To @ZZ whom t may concern:

Be it known that I, WILLIAM M. HonRLE, a resident of Allegheny, in thecounty of Allegheny and State of Pennsylvania, have ingvented a new anduseful Improvement in Chimney-Raising Devices; and I do hereby declarethe following` to be a full, clear, and exact description thereof.

My invention relates to chimney-raisers for io lamps, its object beingto provide a simple form of chimney-raiser which can be formed inconnection with the outer wick-tube and which provides guiding means forthe wicksleeve of the wick-raiser, so performing the i double functionof providing means for locking the chimney-gallery in its raisedposition for lighting the lamp or in its lower or normal position whenthe light is burning and at the same time guiding the wick-sleeve in zoits movement within the outer wick-tube. To this end it comprises,generally stated, an outer wick-tube having a double-bayonet depressionprojecting inward, the inner face of which acts or aids in centering thewieksleeve, and a chimney gallery carrying a sleeve provided with aninwardly-projecting lug to engage with the double-bayonet depression onthe outer face of the wick-tube and provide for holding thechimney-gallery o in either raised or lowered position, the upper endofthe wick-tube being of smaller diameter than the body containing suchdouble-bayonet depression and'being cylindrical, so as to provide forthe proper exposure of the wick.

To enable others skilled in the art to make and use my invention, I willdescribe the same more fully, referring to the accompanying drawings, inwhich- Figure lis a side view, partly broken away, showing thechimney-gallery in raised position. Fig. 2 is a like view showing thesame in lowered position. Fig. 3 is a cross-section on the line 3 3,Fig. l, showing the means for 4,5 guiding the wick-sleeve. Fig. et is atop view of the burner, the chimney-gallery being removed; and Fig. 5 isa section on line 5 5, Fig. 4C.

Like characters indicate like parts in each 5o of the figures.

The invention may be employed with alamp of any suitable constructionhaving a central tube and employing an outerwick-tube d, and the burnerhas the usual body provided with the perforated base b and may have anysuitable form of wick-raising device, the wickraising device shownhaving a wick-sleeve o, which is raised and lowered by means of thepinion o engaging the rack p, secured at its lower end to thewick-sleeve c by means of the pivot q, as shown in dotted linesin Fig.5. The wick tube c travels within the outer wick-tube d and is providedat its upper end with `teeth r, which take into the wick, the latterbeing held between the wick-sleeve c and the central tube of the lamp.(Not shown.) It will be noticed that the upper end e oi' the outerwick-tube is of smaller diameter than the main body thereof and forms acylindrical lip of even edge and continuous circular form, which t isnecessary for the proper exposure of the lamp-wick. In the main body ofthe outer wick-tube below such lip portion e are thedouble-bayonet-joint depressions f, each depression having, as shown,the entrance-groove l, a lateral groove 2 for holding thechimney-gallery in raised position, the vertical groove 3, and thelateral groove 4, which holds the chimney-gallery in its lowered ornormal position. The bases of these grooves are about on a line with theouter face of the cylindrical lip e, so that the supporting-collar oflthe chimney-gallery g can pass over such outer cylindrical lip to engagewith the bayonet joint. The gallery g has thereon the depending collarh, of diameter to t neatly the main body of the outer wick-tube d, sothat it may slide down over the same. This depending collar 7L issecured to the chimney-gallery g by suitable arms lc, leaving spaces t'between the chimney-gallery and collar for the passage of the match inthe lighting of the lamp when the chimney-gallery is raised. The collar7i has the depressions or inwardly-extending lugs n formed therein toenter the bayonetgrooves on the main body of the outer wicktube, soproviding the engaging member between the chimney-gallery and outerwicktube. Such lugs in placing the chimney-gallery upon the lamp travelrst down grooves l until the lugs strike the lateral groove 2,

which forms a support for the chimney-gallery, holding it in its raisedposition and providing for the passage of the match through the spacest' for the lighting of the lamp. By turning the chimney-gallery a shortdistance to one side the lugs n are brought into line with the verticalgroove 3, when the chimneygallery can slide down over the Wick-tube Ctuntil the lugs n strike the lateral grooves 4, When by a short turn thechimney-gallery is locked in its lowered position. To raise it forlighting, it is only necessary to carryit in the reverse direction-thatis, slide the lugs n laterally in the grooves 4, raise the gallery untilthe lugs come in line withthe grooves 2, and turn it slightly, so as tolock it in its raised position, and it may of course be withdrawn fromthe lamp, the lugs n traveling through the grooves l When desired.

It Will be noticed that the wick-sleeve c travels Within the outerWick-tube and is of but slightly-smaller diameter than the cylindricallip at the top thereof. On account of the reduced upper lip of thewick-tube it is necessary to have some guiding means for theWick-sleeve, and the bayonet-joint depres sions f provide guideways forthe Wick-sleeve in its movement Within the Wick-tube. These guidewaysmay of course be supplemented by other depressions formed in the body ofthe wick-tube, such as the vertical depressions m, if that is foundnecessary. One of the depressions m forms a guide against which the backof the rack p bears to hold the latter in engagement With the pinion o.

In this Way I provide a very simple form of outer-Wick-tube constructionhaving the cylindrical upper lip and the guideways for the Wick-sleeve,while the chimney-raising 4device is formed by the simple means ofdepressed guideways in the outer Wick-tube and depressed lugs in thecollar of the chimneygallery, both of which can be formed Without theaddition of any metal to the lamp parts whatever and practically Withoutadditional expense to the lamp, as the depressed guideways and lugs areformed by the maits main body portion, of a Wick-sleeve Inovingwithinthe outer Wick-tube, and guided by the bayonet-joint guideways, and achimneygallery provided with a collar litt-ing over the outer Wick-tube,and carrying lugs adapted to engage with the said bayonet-joint guide-Ways; substantially as described.

2. The combination of an outer Wick-tube having a main body portion andabove the same a cylindrical lip of smaller diameter than the main bodyportion and having depressed bayonet-joint guideways formed in the mainbody portion, a wick-sleeve moving Within the outer Wick-tube and guidedby the bayonet-joint guideways, and a chimneygallery adapted to engageWith the bayonetjoint guideways.

In testimony whereof I, the said WILLIAM M. I-IOERLE, have hereunto setmy hand.
